Out-of-bounds Read

CVE-2024-6505

Medium
6.8/10

Summary

A flaw was found in the virtio-net device in Qemu. When enabling the RSS feature on the virtio-net network card, the "indirections_table" data within RSS becomes controllable. Setting excessively large values may cause an index out-of-bounds issue, potentially resulting in heap overflow access. This flaw allows a privileged user in the guest to crash the QEMU process on the host. This affects qemu versions v5.1.0-rc0 through v5.2.0, v6.0.0-rc0 through v6.2.0, v7.0.0-rc0 through v7.2.13, v8.0.0-rc0 through v8.2.6, v9.0.0-rc0 through v9.0.2 and v9.1.0-rc0.
